Calin Cartis

I build websites, apps, and AI agents that people rely on.

I'm a full-stack engineer who's been shipping production software since 2022. If you have something you want to build, automate, or improve, I can take it from first idea to launch — and I'd love to hear about it.

A few examples of the busywork I can take off your plate.

Services

What I can do for you

Whether you're starting from scratch or improving what you already have, here's where I can help.

  • Websites

    Your online presence should work as hard as you do. Whether starting from scratch or refreshing what you have — fast, clean, and worth sharing.

  • eCommerce

    Ready to sell? I'll build a smooth storefront — product pages, cart, payments — so customers can buy with confidence and you can focus on running the business.

  • Web & Mobile Apps

    Got an idea that's been sitting in a doc? Let's get it in front of real people — on the web, on their phones, or both. I'll ship an MVP fast enough to test and solid enough to grow.

  • Now

    AI Agents

    Let AI take over the busywork. I build agents that answer customers, qualify leads, process documents, or run multi-step tasks across your tools — grounded in your own data, and smart enough to hand off to a human when it matters.

  • Integrations

    Your tools shouldn't need babysitting. I'll connect your CRM, forms, bookings, emails, payments, and third-party APIs — or plug AI into the workflows you already have — so the repetitive stuff runs on its own.

  • Consulting

    Not sure what to build yet? I can help you figure out the what and the how — architecture and code reviews, choosing the right stack, or finding where AI actually makes sense for your business. A single call or ongoing advice, whatever fits.

Process

How we'll work together

No black boxes. At every step, you'll know what's happening and what comes next.

  1. Tell me what you need

    Send a quick message about what you're building — or what's slowing you down. If I'm not the right fit, I'll tell you straight away.

  2. Get a clear plan

    Before any work starts, you get a written scope, timeline, and estimate — so you know exactly what you're getting, and when.

  3. See it take shape

    I build in small steps and share working previews along the way, so your feedback shapes the result early — not after it's done.

  4. Launch and grow

    I handle the launch, hand over everything you need to own it, and stay around for fixes, improvements, and whatever comes next.
